Improvements on the 'make realclean' target.  Some are style improvements,
but the biggest issue is that there are situatons when
${.OBJDIR} == ${.SRCDIR}, and in those situations the previous version
would happily remove all your /usr/src while it was cleaning out the objects.
Not that *you* would be happy about it...  Thanks to bde for immediately
noticing this serious possibility.

More improvements will be made to this target, but I wanted to commit this
safer version right now, before anyone lost their /usr/src due to it.
